What smouldering senses in death's sick delay
Or seizure of malign vicissitude
Can rob this body of honour, or denude
This soul of wedding-raiment worn to-day?
For lo! even now my lady's lips did play
With these my lips such consonant interlude
As laurelled Orpheus longed for when he wooed
The half-drawn hungering face with that last lay.
I was a child beneath her touch,--a man
When breast to breast we clung, even I and she,--
A spirit when her spirit looked through me,--
A god when all our life-breath met to fan
Our life-blood, till love's emulous ardours ran,
Fire within fire, desire in deity.
It was this sort of poem that led Rossetti to being attacked as a member of the 'fleshly school of poetry'; I think it's probably his best poem of this sort. The most famous example, though, is probably "Nuptial Sleep," which describes the sleep after sex:
At length their long kiss severed, with sweet smart:
And as the last slow sudden drops are shed
From sparkling eaves when all the storm has fled,
So singly flagged the pulses of each heart.
Their bosoms sundered, with the opening start
Of married flowers to either side outspread
From the knit stem; yet still their mouths, burnt red,
Fawned on each other where they lay apart.
Sleep sank them lower than the tide of dreams,
And their dreams watched them sink, and slid away.
Slowly their souls swam up again, through gleams
Of watered light and dull drowned waifs of day;
Till from some wonder of new woods and streams
He woke, and wondered more: for there she lay.
